What is Olive Leaf Extract?
Olive leaf extract concentrates the cardioprotective polyphenols of the Mediterranean diet, particularly oleuropein and its breakdown product, hydroxytyrosol, into a single supplement. Clinical trials demonstrate modest but consistent reductions in systolic and diastolic blood pressure, improved LDL oxidation resistance, and supportive effects on immune function. The standardized extract is more potent than olive oil itself for these markers. Standard dose is 500-1000 mg of extract standardized to 15-20% oleuropein, taken with a meal.
